[BUG] COM Port Selector doesn't refresh when it should on some platforms

[SeongGino]

Describe the bug
COM Port Selector should be clearing entries with as much as one device entry (not counting the topmost "Disconnect Current Device" selection) when the last device is disconnected. But while this behavior works on Desktop x86 Linux Qt5 & Qt6 (and APPARENTLY now Windows as well?), Linux ARM Qt6 seem more stubborn about this and only seems to refresh the list when more devices are added, rather than less/none.

To Reproduce

1. Open the app
2. Insert a device, wait for UI to update to display it in Com Ports list
3. Remove device
4. Observe the list still showing a device as connected, even if it's not

Expected behavior
Ports Found list should always update to clear the com ports list regardless of adding or removing devices on all platforms

System Info
